This worked out great on my install of 11.1, granted this was not a X299 system but a SuperMicro X8DT6 dual X5680 xeon board, basically a non-EFI Mac Pro from 2010. Booting via OpenCore 0.6.5 Legacy (for BIOS only systems). So this should be a viable candidate for a quirk of some kind of the OC...
fixed USB ... had to update / correct the config patch and added XHCI-Unsupported.kext and the USB inject all kext from rehabman and remove the x99 USB injector kext.
Now USB 2 and 3 devices work correctly and all attach under the USB 3 driver as expected / desired.
I guess I could complain...
I've recently set this up and there are some learning curves with this build.
Still no power management, stuck at 3.5Ghz (can't turbo, or downclock in idle state) even though x86platform shim seems to load.
Can't run more than 1 dedicated GPU but at this point I no longer need to do so due to...
Just flash the 2.36 bios version. It doesn't have a functional white list. Meaning all cards work due to a firmware bug from Lenovo.
If it's not the correct version I'll let you know when I get home.
Works fine as the OS has no control over it, you manually toggle it on / off via the Fn+spacebar key combo. No DSDT edits needed as it is handled outside of OSX.
These are the paths to the 3 files I created for the 5 monitors I have (3 of 5 are identical models) I believe they are in the correct path as I said I was able to change the name of the display to more accurately reflect the monitor...
While I didn't order mine from eBay this is the card you want.
Dell Wireless DW1560 Broadcom BCM94352Z M.2 NGFF WIFI Card 6XRYC

Also be sure you are on the correct EFI BIOS version...
Realizing this is posted in Mavericks Laptop section ...
I do have a question if it has been confirmed to work or not work in Sierra.
I've been trying to get this going on a desktop running Sierra and all I've been able to do is get the display name changed, no luck in getting additional HiDPI...
I've not tried to use the external monitor functionality via the display port. I think I used external monitors via the docking station but it's been a while since I've actively used this machine.
I didn't bother with AppleHDA after initial run due to no audio after wake so I've been using voodoohda (which I'm sure is a disappointment to RehabMan).
I'm also not running 10.12 on the T440s.
i placed it where it would have gone if it was all inside the single file. I did include all of the SSDT files if I recall correctly as it has been a while.
This is not something I'd recommend doing based on what I've learned since as it makes this more complex than you need to be but it taught...
I'm not sure yet, I've only updated two of my machines so far and that thread that RehabMan shared shows a lot of issues with Sierra.
The Dell T110 (desktop tower) has been updated, and my unsupported Mac Pro (early 2008) has been updated. I've not had a chance to look at updating the rest...
